What is Estimated Input Latency?

Estimated Input Latency is an estimate of how long your app takes to respond to user input during the busiest 5 second window of page load.

The timing of this audit is from First Meaningful Paint to the end of the trace, which is roughly 5 seconds after Time to Interactive.

If your latency is higher than 50 ms, users may perceive your app as laggy.

To make your app respond to user input faster, optimize how your code runs in the browser.
